The two-unit residential building at 2129-2131 Bay Street in the Marina neighborhood is a 2-story flats and duplex structure built in 1927, currently owned by Monfredini Investments LLC. The property has undergone several significant renovations and maintenance work over the years, with the most recent being a flat roof reroofing project completed in October 2023 at a cost of $21,500. Previous major improvements include a comprehensive kitchen remodeling project in 2011 ($32,472) followed by bathroom remodeling in 2014, during which various plumbing and electrical upgrades were also made, including new fixtures and heating elements.

The building has a documented history of maintenance issues from early 2011, including water damage, floor covering problems, interior surface concerns, and staircase repairs, which resulted in multiple housing violations. However, all these violations were resolved by June 2011. The property has experienced periodic renovations and maintenance work throughout its history, including multiple roofing projects in 1991 and a significant rear staircase repair in 2020 involving replacement of damaged wood steps and risers to meet safety codes.

Earlier improvements include bathroom renovations in 1988 and 2000. The building's maintenance history indicates regular upkeep, with all recent permits (2020-2023) showing completed status, suggesting proper attention to building maintenance and safety systems by current ownership. The violations from 2011 appear to be in relation to age-related wear and water damage, which were promptly addressed and resolved within approximately five months.
